We got a 2500 router and performing NAT on it. For clients coming from inside we perform NAT overload. These source IPs are trying to reach 2 destination servers which are on the outside leg of the router. These destination IP addresses are also being destination NATed. (ex. 126.96.36.199 to 192.168.202.199 and 192.168.170.1 to 10.200.45.70). The problem is two souce IPs , of which 10.95.11.32 reach bot of these destinations but 10.95.11.31 can not reach 192.168.202.199. We have seen in debug ip nat output, that, 10.95.11.31 is not being source NATed when it tries to reach 192.168.202.199. HAs anybody have any comment on this ? Attached is the topology and router config.
